HYDROXYPHENYL THIAZINANE CARBOXYLIC ACID

Description

Hydroxyphenyl thiazinane carboxylic acid is a novel skin-brightening agent that has gained attention in the cosmetic industry for its potent tyrosinase-inhibiting properties. This synthetic compound belongs to the class of thiazinane derivatives and is characterized by its unique molecular structure, which combines a hydroxyphenyl group with a thiazinane ring and a carboxylic acid moiety.

The ingredient works by effectively suppressing melanin production through multiple mechanisms. It primarily inhibits tyrosinase, the key enzyme in melanogenesis, while also interfering with melanosome transfer to keratinocytes. Clinical studies have demonstrated its ability to reduce hyperpigmentation and improve overall skin tone with regular use.

Hydroxyphenyl thiazinane carboxylic acid exhibits good stability in various formulations and is compatible with a wide range of cosmetic ingredients. It is typically used at concentrations between 0.1% to 2% in skincare products such as serums, creams, and lotions. The compound has shown a favorable safety profile in dermatological tests, with minimal irritation potential and no significant adverse effects reported.

This ingredient is particularly suitable for addressing age spots, melasma, and post-inflammatory hyperpigmentation, making it a valuable addition to targeted skincare treatments and overall skin-brightening regimens.
